Description

Technical Field

[0001] This utility model relates to the field of electronic display technology, specifically to an LED display screen with anti-collision function. Background Technology

[0002] LED displays, capable of displaying various information such as text, graphics, images, animations, market data, videos, and recorded signals, are widely used in security monitoring centers, dispatch and command centers, broadcasting studios, high-end conference video centers, and high-definition electronic billboards due to their advantages of large display area, high brightness, vibrant colors, and easy assembly. However, current LED displays have some problems. Many LED displays on the market lack dedicated anti-collision devices, or their anti-collision structures are simple and offer limited protection. This lack of anti-collision functionality makes the screen panel prone to cracking and damage when subjected to external impacts. Internal circuits, chips, and other delicate electronic components can also be damaged by vibration and pressure, affecting display quality, reducing clarity and color accuracy, and even causing the display to malfunction.

[0003] Therefore, LED displays with anti-collision functions are now available, which can eliminate the drawbacks of existing devices. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-5 As shown, an LED display screen with anti-collision function includes: a base 1, a rubber pad 2, an angle adjustment mechanism, and an anti-collision mechanism. The rubber pad 2 is fixedly installed at the bottom of the base 1, and a support base 3 is fixedly installed at the top of the base 1. An angle adjustment mechanism for adjusting the angle of the display screen is fixedly installed at the top of the support base 3, and an anti-collision mechanism for mitigating impact is fixedly installed at the front end of the angle adjustment mechanism.

[0026] In one embodiment, such as Figure 2As shown, the angle adjustment mechanism includes an adjustment bracket 4 fixedly mounted on the top of the support base 3. A first bevel gear 5 is rotatably mounted on the adjustment bracket 4. A motor 6 is fixedly installed inside the support base 3. The output end of the motor 6 is fixedly connected to the central shaft of the first bevel gear 5. A rotating rod 7 is rotatably mounted on the inner wall of the adjustment bracket 4. A second bevel gear 8 is fixedly mounted on the rotating rod 7. The second bevel gear 8 meshes with the first bevel gear 5. A mounting base 9 is fixedly mounted on the rotating rod 7.

[0027] The first bevel gear 5 is driven to rotate by the output end of the motor 6. Then, the first bevel gear 5 drives the second bevel gear 8 to mesh and rotate, thereby causing the second bevel gear 8 to drive the rotating rod 7 to rotate. When the rotating rod 7 rotates, it drives the mounting base 9, which is fixedly connected to it, to rotate. This causes the mounting base 9 to drive the protective bracket 10 to adjust its angle. It can be flexibly adjusted according to the actual situation, and the automatic adjustment method brings convenience to the operator.

[0028] In one embodiment, such as Figures 3-5 As shown, the anti-collision mechanism includes a protective bracket 10 fixedly mounted on the front end of the mounting base 9. A display screen body 11 is slidably mounted on the inner wall of the protective bracket 10. Dovetail tenons 12 are provided on the upper and lower sides of the display screen body 11. A dovetail groove 13 adapted to the dovetail tenon 12 is opened on the inner wall of the protective bracket 10. A first rotating seat 14 is fixedly mounted on the outside of the display screen body 11. A second rotating seat 15 is fixedly mounted on the inner wall of the protective bracket 10. A damper 16 is rotatably mounted on the first rotating seat 14. The end of the damper 16 is rotatably connected to the second rotating seat 15. A spring bracket 17 is fixedly mounted on the circumferential surface of the damper 16. A first spring 18 is fixedly mounted on the top of the spring bracket 17. The end of the first spring 18 is fixedly connected to the output end of the damper 16. A support component for auxiliary buffering is fixedly mounted on the inner wall of the protective bracket 10.

[0029] Mounting base 9 is fixedly located at the middle position of rotating rod 7, and mounting base 9 is fixedly connected to protective bracket 10 by fixing bolts. Display screen body 11 is slidably disposed in dovetail groove 13 on the inner wall of protective bracket 10 by dovetail tenon 12, dovetail tenon 12 and dovetail groove 13 are tightly fitted, and the inner wall of protective bracket 10 is provided with limiting buckle to prevent display screen body 11 from falling off.

[0030] When impacted, the impact force forces the display body 11 to slide against the inner wall of the protective bracket 10. By setting a dovetail tenon 12 on the display body 11, it fits tightly into the dovetail groove 13 on the inner wall of the protective bracket 10, making the connection of the display body 11 stable. When the display body 11 slides, it compresses the dampers 16 installed on both sides. The dampers 16 rotate under the setting of the first rotating seat 14 and the second rotating seat 15, which can be flexibly adjusted according to the position of the display body 11. The damping material in the damper 16 buffers the impact force, and then the first spring 18 drives the output end of the damper 16 to reset.

[0031] The support assembly includes a sliding bracket 19 fixedly mounted on the inner wall of the protective bracket 10, a guide rod 20 fixedly mounted on the outside of the display screen body 11, a sliding plate 21 slidably mounted on the inner wall of the sliding bracket 19, the end of the guide rod 20 being fixedly connected to the sliding plate 21, a second spring 22 being fixedly mounted on the bottom of the sliding plate 21, a polyurethane buffer block 23 being fixedly mounted inside the sliding bracket 19, and the bottom end of the second spring 22 being fixedly connected to the top of the polyurethane buffer block 23.

[0032] When the display body 11 slides, the guide rod 20 drives the sliding plate 21 to slide on the inner wall of the sliding bracket 19 and compresses the second spring 22. Then, with the setting of the polyurethane buffer block 23, the impact force is further buffered to improve the anti-collision capability. Then, the second spring 22 drives the sliding plate 21 to reset, so that the display body 11 slides back to its original position.

[0033] The above embodiments disclose an LED display screen with anti-collision function, wherein: motor 6 drives the first bevel gear 5 to rotate, and through meshing transmission with the second bevel gear 8, drives the rotating rod 7 and the mounting base 9 to rotate synchronously. The mounting base 9 is rigidly connected to the protective bracket 10, and the angle of the protective bracket 10 is infinitely adjustable through the transmission of rotational torque. The protective angle can be automatically adjusted according to the working conditions, significantly improving the ease of operation and adaptability;

[0034] Upon impact, the display screen body 11 slides along the inner wall of the protective bracket 10, with its dovetail tenon 12 forming a stable guiding constraint with the dovetail groove 13 of the protective bracket 10. During the sliding process, the display screen body 11 compresses the dampers 16 on both sides. The dampers 16 adaptively deflect through the hinge structure of the first rotating seat 14 and the second rotating seat 15, and the internal damping material buffers the impact through frictional energy dissipation. The linkage guide rod 20 pushes the sliding plate 21 to compress the second spring 22 and squeeze the polyurethane buffer block 23, forming a secondary buffer protection. After the impact, the first spring 18 and the second spring 22 work together to release elastic potential energy, driving the display screen body 11 and the sliding plate 21 to accurately reset.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
